Abstract
An improved method of forming a non-slip surgical knot for fastening tissue, and the knot prepared by the improved method, are disclosed. A partially tied knot which has a first loop and knot loops formed about the first loop to create a common loop core receiving the first loop is initially provided. The distal end of the suture filament from which the partially tied knot is made is passed through the tissue, and it is then fed through the first loop to form a tissue-fastening loop. The improvement involves pulling the first loop and a portion of the suture filament through the common loop core, thus eliminating the first loop and forming a distal loop positioned adjacent the common loop core. When this improved method is used to form the non-slip knot, a knot with a consistently high knot security can be formed without the need to provide a tension on the suture filament which exceeds the breaking strength of the suture.
